Access to TWINCAT PLC via LabView

[swap15]

Hello,

I want to have access to the TwinCAT PLC variables in Labview.The TwinCAT software and Labview application are running on different PC's.

In my Labview application I want to have access to the TwinCAT PLC variables. Does anyone have any idea about how to do it? or any sample examples?

Any help would be appreciated.

Thanks in advance

Normally you put up a OPC Server on the Pc on which your twincat is installed. There are a number of helpful links how you can set up an OPC Server with Twincat.

This Server broadcasts the values over the network.

Once you have broadcasted the values you can use these in LabVIEW using the datasocket supervisory Controll Tookit.

Be aware not all OPC Servers are supported.
